FLAUNTING IT: The girls received a lot of disapproving comments from viewers [PA]

The troupe were accused of being too “pornographic’’ for Saturday evening telly.

But they responded by posing in sexy lingerie.

The sizzling group, who looked like they were naked in flesh-coloured body stockings, wowed the TV judges and the audience by dancing to Feeling Good.

Simon Cowell, 54, told them: “It was very Vegas.

"It was a spectacle.”

However some viewers were disgusted.

One blasted that acts were getting “more pornographic”.

Another wrote: “This explicit content should not even be aired knowing families watch the show!!!”

One mum added: “This is how young children begin to think that ‘sexy’ is the answer.

“We are dancers!”

Steph Morville hits back at the criticism

“It normalises this ­behaviour if children see it on family shows.

"I want my daughter to be a lady not sleazy.”

Another viewer said: “Soooo inappropriate.”

However Crazy Rouge dismissed the criticism.

Member Steph Morville branded the comments as “cringe” and pointed out: “We are dancers!”

Fellow member Gabriella Paul also claimed viewers actually missed out on seeing more of their act as their performance was edited to a short segment.

Last night a show spokeswoman said: “As a family show we always make sure any acts shown are suitable viewing.”

There are also fears that the 9pm TV ­watershed, which is meant to protect children from scenes of sex, violence and bad language, is not working as kids can still see adult shows on “catch-up’’ services on the internet.

Now the Department for Culture, Media and Sport has said it would “consider’’ new legislation if the ­industry failed to develop its own safeguards.

Meanwhile it has been revealed a member of BGT swing band Jack Pack has sung on stage with Michael Bublé, 38.

Alfie Palmer, 24, who used to work as a Bublé tribute act, managed to get on stage at one of the superstar’s gigs four years ago and the pair sang Home together.
